a:-

f(x)=2x+3

$\\ \rm\Rrightarrow f(1)=2(1)+3=2+3=5$

$\\ \rm\Rrightarrow f(-5)=2(-5)+3=-10+3=-7$

$\\ \rm\Rrightarrow f(a)=2a+3$

$\\ \rm\Rrightarrow f(a+2)=2(a+2)+3=2a+4+3=2a+7$

$\\ \rm\Rrightarrow f(b)=2b+3$

b:-

f(x)=x+4

$\\ \rm\Rrightarrow f(-2)=(-2)+4=2$

$\\ \rm\Rrightarrow f(3)=3+4=7$

$\\ \rm\Rrightarrow f(7)=7+4=11$

Summer Dave builds a crate to hold vegetables the volume of the crate is 48 ft.³ the base area of the crate is 16 ft.² what is t

MariettaO [177]

The height of crate is 3 feet

Solution:

Given that Summer Dave builds a crate to hold vegetables

Volume of crate = 48 cubic feet

Base area of crate = 16 square feet

To find: height of crate

The crate is of shape cuboid

The volume of cuboid is given as:

$volume = length \times width \times height$

We know that,

$Area\ of\ base = length \times width$

Therefore, volume becomes,

$volume = base\ area \times height$

Substituting the given values we get,

$48 = 16 \times h\\\\h = \frac{48}{16}\\\\h = 3$

Thus height of crate is 3 feet

Earth revolves around the Sun in 365 days, but the planet Mercury does so in only 88 days. Compared to Earth, how many more comp

Elena L [17]

Answer:

In a 1000 days Mercury will make 8.624 more revolutions than Earth!

Step-by-step explanation:

Earth takes 365 days to make a complete revolution.

we can say that the rotational speed of Earth is $\dfrac{1}{365}\frac{\text{rev}}{\text{day}}$

so, in a 1000 days how many revolutions will Earth have made?

$\dfrac{1}{365}\frac{\text{rev}}{\text{day}}\times(1000\,\text{day})$

see that the 'day's cancel out. Simply multiply the two numbers!

$2.739\text{rev}$

Next, do the same for Mercury

we can say that the rotational speed of Mercury is $\dfrac{1}{88}\frac{\text{rev}}{\text{day}}$

as it completes 1 revolution in 88 days.

so, in a 1000 days how many revolutions will Mercury have made?

$\dfrac{1}{88}\frac{\text{rev}}{\text{day}}\times(1000\,\text{day})$

multiplying by 1/88 by 1000 yields:

$11.363\text{rev}$

The Question is how many MORE complete revolutions will Mercury make in 1000 days?

We need to subtract the revolutions of Mercury with Earth to find how far ahead is Mercury from Earth

$11.363\text{rev} - 2.739\text{rev}$

$8.624\text{rev}$

In a 1000 days Mercury will make 8.624 more revolutions than Earth!

-3x + y = -14 x= -2y + 14 Which variable should an expression be substitute for?

ICE Princess25 [194]

9514 1404 393

Answer:

Step-by-step explanation:

There is already an expression given for x, so that is the easiest variable to substitute for.

Substituting for x using the second equation, you have ...

-3(-2y+14) +y = -14

6y -42 +y = -14

7y = 28

y = 4

x = -2(4) +14 = 6

The solution is (x, y) = (6, 4).

_____

Substitution for x is the easiest.

The first equation could be rearranged to give an expression for y:

y = 3x -14

Then that can be used to substitute for y in the second equation. My lazy brain judges that to be more work.
